, terrigenous sediments
are those derived from the erosion of rocks
on land; that is, that are derived from terrestrial
environments.(Pinet, 79) Consisting of sand
, and silt
carried to sea by rivers
, their composition is usually related to their source rocks; deposition of these sediments is largely limited to the continental shelf
Sources of terrigenous rocks include volcanoes, weathering of rocks, wind-blown dust, grinding by glaciers, and sediment carried by icebergs.
75% of sediments are terrigenous- it is present everywhere.
These are transported by wind, rivers and icebergs.
